Hi again, anyone know if itīs ok to use 19 tube or 25 square instead of 19 square on D1 to D4?
Thanks,
Samy

If chris comes along I am sure he will be able to tell you but you might be better off asking at the Haynes Roadster Forums

Yeh , Iīve been looking up some stuff on Haynes forum ,thereīs alot of good info on there & Chris has really been a great help
Thanks ,
Samy

Should be no problem using 25 square, it's just heavier.

Cheers

Chris
